Enhancements can be done mainly in 3 ways:
- Old User-exit forms in predefined includes
- Enhancements and function module user-exits
- Badi's.
In ECC60 (Netweaver 2004s) you can also use the enhancement framework to create enhancements almost anywhere...
Examples:
For BAdI, take a look at the definition LE_SHP_DELIVERY_PROC.
There you will find an example implementation class (in SE19), CL_EXM_IM_LE_SHP_DELIVERY_PROC
method if_ex_le_shp_delivery_proc~change_field_attributes .
data: ls_field_attributes type shp_screen_attributes,
ls_xvbup type vbupvb.
* Example 1: The field 'Actual goods-movement date' should not be
* changed by the user
ls_field_attributes-name = 'LIKP-WADAT_IST'.
ls_field_attributes-input = 0.
append ls_field_attributes to ct_field_attributes.
* Example 2: The material description should not be changed for a
* certain group of materials after completion of the picking process
if is_lips-matnr cs 'ZZ'.
read table it_xvbup into ls_xvbup with key mandt = is_lips-mandt
vbeln = is_lips-vbeln
posnr = is_lips-posnr
binary search.
if ls_xvbup-kosta eq 'C'.
ls_field_attributes-name = 'LIKP-WADAT_IST'.
ls_field_attributes-input = 0.
append ls_field_attributes to ct_field_attributes.
endif.
endif.
endmethod. "IF_EX_LE_SHP_DELIVERY_PROC~CHANGE_FIELD_ATTRIBUTES
IN SE38 you can go to old user exit technology used in sales order processing: Ex: include MV45AFZZ
*---------------------------------------------------------------------*
* FORM USEREXIT_FIELD_MODIFICATION *
*---------------------------------------------------------------------*
* This userexit can be used to modify the attributes of *
* screen fields. *
* This form is processed for each field in the screen. *
* *
* The use of the fields screen-group1 to screen-group4 is: *
* *
* Screen-group1: Automatic modification contolles by transaction*
* MFAW. *
* Screen-group2: Contents 'LOO' for steploop-fields. *
* Screen-group3: Used for modififaction, which are dependent on *
* control tables or other fix information. *
* Screen-group4: Unused *
* *
* For field mofifications, which are dependent on the document *
* status, you can use the status field in the workareas *
* XVBAP for item status and XVBUK for header status. *
* *
* This form is called from module FELDAUSWAHL. *
* *
*---------------------------------------------------------------------*
form userexit_field_modification.
* CASE SCREEN-GROUP3.
* WHEN '900'.
* IF VBAK-VBTYP NE 'A'.
* SCREEN-ACTIVE = 0.
* ENDIF.
* ENDCASE.
* CASE SCREEN-NAME.
* WHEN 'VBAK-VBELN'.
* SCREEN-ACTIVE = 0.
* ENDCASE.
endform.
Now you need to spend sometime on a system to figure it out.
Good luck,
